Science fiction is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life.
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time.
Technology is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.
Genre is any category of literature, music, or other forms of art or entertainment, whether written or spoken, audio or visual, based on some set of stylistic criteria.

Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas."
Innovation can be defined simply as a "new idea, device or method".

It usually avoids the supernatural, and unlike the related genre of fantasy, historically, science-fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction.
The supernatural is defined as being incapable to be explained by science or the laws of nature, characteristic or relating to ghosts, gods or other supernatural beings or to appear beyond nature.
Fantasy is a fiction genre that uses magic or other supernatural elements as a main plot element, theme, or setting.
